Poor Man's OSS Helix Silencer

thingiverse

You see revolutionary product on the Internet. What do you do? Buy it? Nah, that's too easy. Of course you copy it! I made it loosely based on OSS Suppressors, but it still keeps key feature: instead of keeping gases inside and later blowing them on your face it diverts them into helical passages around main part, allows them to cool down and and slowly vent forwards. This helps to reduce noise even more and reduces pressure inside silencer and barrel which leads to reduced blowback. Also I managed to more or less replicate nice looking end cap. For more info, rest of the .STLs, parts list and assembly guides refer to my [previous silencer design][base]. **Slim version** ~~clearly not a RAD 22 rip-off~~ All baffles and caps have it's own helical grooves on outer shell, these come in few options: - normal or rod - you can decide if you want baffles flying around or held together by m3 threaded rod - baffles can be either uniform all the way round or have hole which disturbs gases flow making silencer more effective - 2 versions of end caps, either one works the same, they just look different - normal blast baffle and reinforced one, normal is in the same row as normal baffle (stl). To keep it simple I've included everything inside 2 files so you'll have to delete unnecessary parts. I suggest using stronger blast baffle with rod and baffles with holes. If you use rod version when assembling tighten it until it has slight curve, then just push everything inside. I noticed that some of the baffles like to melt with each other but I'm to lazy to address this issue. Silencer still works fine so that's not much of an issue. Only parts you'll require are slim base, slim locking nut and locking rings found [here][things]. For assembly refer to instructions found [here][base]. Keep in mind that pipe's length will be different - again, the goal is that distance between blast baffle and end of the tube is 34 mm. **Fat version** It just adds new cap and helical rings inside outer chamber, baffles in inner one stay the same as in [previous one][base], so it's very easy to upgrade this one. Each ring has one groove longer a bit so they index with each other. Bottom ring is press fit on PVC pipe and in theory everything should be pressed together by gases, so no additional fasteners are required. Keep in mind that these probably won't survive .223 so use only for .22lr or similar and airsoft.
